I know I have not been too active on this blog lately. I just wanted to say that I am still here, just busy. We went on vacation in November, and since we've been back it has been one project after another! And now...we are all getting over a cold. I expect to be more active in posting after the New Year.

The girls experimented with liquid density. They used soap, water, and shampoo and a marble to demonstrate which one is more dense. They found out by dropping a marble into a tube filled with one of the solutions and timing it's decent. The shampoo won; it had the slowest time.

They made some paint impressions of fish.

And extracted the beta carotene from carrots.

They experimented with mixing colors.

And saw how to seperate colors.

The girls learned about surface tension and dissolving.

And tested for acids, bases, or neutrals.

Georgia's hypothesis was correct, Sprite is an acid. It turned red when she added the purple cabbage juice.

Olivia found out that Amonia is a base. It turned blue.

Vinegar is an acid. Then Georgia added some baking soda to it. Bakind soda is a powdered base. The acidity in the vinegar turned to neutral.

We saw how good, or not so good, we washed our hands with a special lotion that shows GERMS on your hands when placed under a black light.

And they made some paintings and changed the colors using different chemicals.

Celebrate the science behind chemistry at the Museum. Taste liquid nitrogen ice cream, watch as a “genie” emerges from a bottle, choose from a dozen hands-on experiments or do them all! Children can complete a passport for a chance to win prizes.

Today, we had fun reading about Halloween traditions, scary stories, and fun facts about the holiday. We also read a story about Stingy Jack, and learned the history of the jack-o-lantern.

Georgia received an invitation to attend the Park PALS & Friends picnic on Sunday at the Nature Center.

After a mixer activity, and supper, the kids played some games.

Georgia also received an award for her attendance at her nature classes.

Next...we were off on a hayride!!

The hayride was a lot of fun...and we got to see parts of the park that we had never been to...it is HUGE. The naturalist that was driving the tractor stopped periodically to tell us about what we were seeing, or to explain things they did there...such as prairie burning.

Here, he is telling us about the different plants found on the prairie, such as the Indian Grass.
